It doesn't appear that the base is yet available separately so you may want to return the camera and purchase a one camera system instead if you want the hardware features of the Pro base.</P> Tue, 10 Jan 2017 14:05:37 GMT https://community.arlo.com/t5/Arlo-Pro/Arlo-Pro-Alarm/m-p/1205892#M5178 jguerdat 2017-01-10T14:05:37Z
